Liking cljdoc? Tell your friends :D

copy-deps

copy-deps is a Leiningen plugin to copy dependencies into your project's resources. This is necessary in the case of Java agents for example, which have to be present as jars outside the uberjar, or native library dependencies.

Usage

In your project.clj, in the :plugins section, add:

To run this plug in, execute:

$ lein copy-deps

If you want the task to run automatically, which is recommended, add:

:prep-tasks ["javac" "compile" "copy-deps"]

and it'll be invoked every time you build your uberjar. The essential plug-in configuration goes into your project.clj and looks like this:

:copy-deps {:destination "resources/jars"}

:destination specifies where to copy the jars. You can then specify the jars you want to copy in this fashion:

:copy-deps {:dependencies [[org.clojure/clojure "1.7.0"]]
            :destination  "resources/jars"}

or, if you have :java-agents in your project, there's a shortcut to just copy them:

:jar-copier {:java-agents true
             :destination "resources/jars"}

They can both be mixed if desired.

A full example using Java agents can be found in proclodo-spa-server-rendering:

(defproject proclodo-spa-server-rendering "0.1.0-SNAPSHOT"
  :dependencies [[org.clojure/clojure "1.7.0"]]
  :plugins [[jar-copier "0.1.0"]]
  :prep-tasks ["javac" "compile" "jar-copier"]
  :java-agents [[com.newrelic.agent.java/newrelic-agent "3.20.0"]]
  :copy-deps {:java-agents true
              :destination "resources/jars"})
